  • black smoke removal filters have the drawbacks that, when used for a long time, they get clogged up by the black smoke which they collect and pressure loss is increased.
  • this electrostatic diesel particle filter consists of: a generally tubular flow chamber 1; a corona electrode 2 consisting of a very fine linear body such as a tungsten wire stretched along the flow chamber axis in this flow chamber 1; a cylindrical isolating electrode 3 arranged facing this corona electrode 2; and a voltage source 4 whereby high voltage is applied between corona electrode 2 and isolating electrode 3.
